EVENER-BOARD FOR BOOKBIN DIN G-MACHINES.

Specification of Letters Patent.

Patented July 3, 191%.

Application filed April 27, 1914. Serial No. 834,587.

To all whom it may concern:

Be it known that I, CHARLES F. MOBEE, a citizen of the United States,residing in Athens, county of Athens, and State of Ohio, have invented anew and useful Improvement in Evener-Boards for Bookbinding-Machines, ofwhich the following is a specification.

This invention relates to binding machines of the class in which loosesheets placed, evened, and perforated and in this manner prepared forthe binding process which is also perfected before the sheets areremoved from the machine.

The object of my invention is to provide an adjustable evener board forbinding] machines so that the perforations to be made in the sheets tobe bound may be placed at such a distance from the edge of the sheets asmay be desired.

My invention consists of certain details of construction hereinafter setforth, pointed out in my claims, and illustrated in the accompanyingdrawings in which Figure I shows a perspective view of a part of abiniding machine fitted out with my device; an

Fig. II shows a sectional view of the same.

Referring to the accompanying drawings the reference numerals 10 and 11are used to indicate the forward standards of a bind ing machine and thenumeral 12 the pressure bar designed for upward and clownward movementtherein. The numeral 13 indicates the slot in the pressure bar designedas a guide for a bit (not shown) by means of Which perforations arebored through the sheets 14, to be bound. The sheets rest on the baseplate 15, and the eX tension removable base 16.

The foregoing references relate to old constructions of binding machinesand are only shown and described herein to form a basis for myinvention.

y invention consists of an evener board 17 designed to, when in place,constitute a wall against which the sheets are forced for evening theedges thereof. The construction of the evener board must be such that itcan be removed so as to be out of the way while the binding process isgoing on. Also it is often desirable to have the perforations fartherfrom the forward edge of the sheets than is ordinarily done. My deviceprovides are for both of these objects by the following construction Thenumerals 18 and 19 indicate like bars mounted in advance of, andparallel to, the standards 10 and 11, respectively, a space being leftbetween each bar and its respective standard. The lower end of each baris provided with a lug which extends through a longitudinal slot in itsrespective base members 20 and 21, and is held in any desired positionin the slot by means of a set screw 22. To the upper extremity of eachbar is secured a right angular, rearwardly extending arm, 23 and 24,respectively, each arm provided with a longitudinal slot through which aset screw 25 passes and is secured in. its respective standard. By thisconstrue tion it is obvious that the bars 18 and 19 may be set at anydesired distance from the standards, within the scope determined by thelength of the slots in the arms and the base. The upper extremity ofeach bar is provided with a recess 26 and 27, respectively, designed asseats for lugs 28 and 29, respectively, secured as shown, on the evenerboard 17.

The numerals 30 and 31 indicate lugs or trunnions, extending outwardly,one from each lower end of the evener board, said lugs being designed toengage in their respective slots between the standards 11 and 12 and thebars 18 and 19 respectively, and to travel upwardly and downwardlytherein. When the evener board is in place operating to even the sheetsplaced in the binding machine the lugs 28 and 29 are resting in theirseats 26 and 27 respectively, obviously the evener board being suspendedtherefrom.

en it is desired to remove the evener board it is raised upwardly untilthe lugs 28 and 29 are released, the upper end then pulled outwardly andthe board then moves downward of its own weight, the lugs 30 and 31,traveling in their respective slots, until the board assumes theposition shown in the drawings.

When it is desired to have the perforations to be made in the sheetsfarther than the ordinary distance the bars 18 and 19 are movedoutwardly to the desired point and there secured in the mannerhereinbefore described. It is obvious this operation will secure thedesired result.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is:

1. A book binding machine comprising a frame including a base plate andsupporting standards extending above and below the plate, a vertical barsecured to each standard in spaced relation thereto to provide avertical space extending above and below the base plate, and an evenerboard having trunnions slidably engaged in the vertical spaces providedbetween the standards and bars to permit of sliding and pivotal movementof the evener board, and means on the latter to engage the bars andsupport the board in cooperating relation with the base plate.

2. A. book binding machine comprising a pair of base members havingslots, standards secured to the members, a base plate carried by thestandards, a vertical bar adjustably secured in the slot of each basemember for movement toward and from adjacent standard, and an evenerboard having parts engaged between the bars and standards whereby saidevener board may be moved to and from a position adjacent the baseplate.

3. A book binding machine comprising a pair of base members each havinga h0rizontal slot, a standard rising from each member, abar for eachbase member adjustably secured at its lower end in the slot of sailmember, means adjustably securing the upper end of each bar to theadjacent standard, an evener board slidably and pivotally engaged withthe bars, a base plate supported by the standards, and-means for holdingthe evener board on the bars against movement and in cooperativerelation with the base plate. 7

4. A book bindingmachine comprising a base plate, standards adjacent theplate, vertical bars arranged in advance of the standards, adjustableconnections between the standards and bars whereby the spacing of thebars from the standards may be varied, the upper ends of the barsbeingprovided with seats, an evener board provided with trunnionsslidably engaging the bars, adapted to engage in to support the evenerbase plate.
